Affleck will join his Batman v Superman: Dawn of Justice co-stars and director Zack Snyder at Comic-Con, the annual fan convention in San Diego, where the cast of the hotly-anticipated comic clash was introduced last year.

Affleck will make his debut as the Dark Knight in the film, out next March. The actor was joined by Snyder, Superman Henry Cavill, and Wonder Woman Gal Gadot at last year’s Comic-Con, where fans were shown the first footage from the film. This year, co-stars Amy Adams, Jesse Eisenberg, Jeremy Irons and Holly Hunter will also be joining the panel, which will take place Saturday morning at 10:30 a.m. in the convention’s hallowed Hall H.

The Comic-Con announcement comes just one day after Affleck and Garner revealed that they were splitting up.

"After much thought and careful consideration, we have made the difficult decision to divorce," the couple said in their statement to ET. "We go forward with love and friendship for one another and a commitment to co-parenting our children whose privacy we ask to be respected during this difficult time. This will be our only comment on this private, family matter. Thank you for understanding."
